Physiology is a scientific study of the normal mechanical, physical, and biochemical functions of living organisms such
as human, animals and plants, or their constituent tissues or cells. It includes the study of an organism's vital functions
and processes, for example movement, reproduction, growth and development, the absorption and processing of
nutrients, the synthesis and distribution of proteins and other organic molecules,and the functioning of different tissues,
organs, and other anatomic structures. The word "function" is important because physiology traditionally had to do with
the function of living things.

Physiological processes are dynamic. Cells change their function in response to changes in the composition of their
local environment, and the organism responds to alterations in both its internal and external environment. Many
physiological reactions are aimed at preserving a constant physical and chemical internal environment.

Human physiology today is a science of wide scope. Some physiological studies are concerned with processes that
happen within cells. The physiology of cells is called cell physiology. Other physiological studies deal with how tissues
and organs work, how they are controlled and interact with other tissues and organs and how they are integrated within
the individual. Yet other physiological studies deal with how we respond to our environment, for example, to extremes of
temperature (in arctic conditions versus the desert) and to changes in pressure (deep under the ocean versus weightless
in space). Human physiological processes are the functions of living persons and their parts, and the physical and
chemical factors and processes involved.
